Neuromorphic computing: Bringing the Power of the Human Brain to AI Systems.
Artificial intelligence (AI) has come a long way since the 1950s. Initially, AI systems could only perform basic tasks such as calculation and pattern recognition. But with time and advancements in technology, AI systems have evolved and can now perform complex tasks such as language translation, face recognition, and even art creation. But despite these advancements, most AI systems still rely on the traditional Von Neumann computing architecture. This architecture has limitations, such as high energy consumption, inability to handle complex data structures, and the need for high bandwidth communication channels between the CPU and memory. Neuromorphic computing is a new computing paradigm that seeks to overcome these limitations by emulating the human brain’s structure and function. In this article, we will explore more about neuromorphic computing, how it works, its benefits, challenges, tools, technologies, and best practices for managing it.
What is Neuromorphic computing?
As mentioned earlier, neuromorphic computing is a new computing paradigm that mimics the human brain’s structure and function. The human brain has been a source of inspiration for AI researchers for decades because it is highly efficient in processing and storing information. The human brain consists of about 100 billion neurons, and each neuron connects to thousands of other neurons through synapses. These connections allow the brain to process and store massive amounts of information using minimal energy.
Neuromorphic computing aims to replicate the structure and function of these neurons and synapses to create highly efficient AI systems. In neuromorphic computing, the basic computing unit is called a spiking neuron. A spiking neuron is a mathematical model that describes how neurons in the brain communicate with each other using electrical signals. The communication between neurons occurs through spikes, which are brief bursts of electrical activity. These spikes carry information that can be used to represent data, such as images, sounds, and text.
The communication between neurons in neuromorphic computing is modeled using an event-based approach. In this approach, spikes occur only when there is a change in the input signal. This means that the system only uses energy when there is information to be processed, unlike in traditional computing, where energy is consumed continuously.
